OK, so here's what my iPod has started doing....I plug it into my PC, and nothing. It doesn't charge, Windows doesn't see it. I removed Apple Mobile and iTunes, and reinstalled, just to cover it all, still nothing. I also run (dual boot) Linux. In Linux, nothing. I have tried all 4 of my USB ports. Won't charge or connect on any. However..... I have a USB wall charger (Nexxtech adapter that the USB SYNC cable plugs into) and it charges just fine. So I am wondering, why would it charge from the adapter but not from the PC? I have confirmed that the USB ports work using other devices.
